In certain of the figures, have omittedthe showing of certain detailsin-order to make the disclosure readily understandable i It is to be understood that the form of my invent-ion, herein illustrated, is intended to be attached to the right hand side of a binder having a right hand bundle-delivery.

The structure, briefly described,comprises a frame work having two parallel valleys-into which the bundles are dropped alternately from'the binder, a means for packing the bundles into the dumping recept-acle'and means for quickly 'dumping the receptacle when it is full, at the same-time swinging the sions 14 from the binder frame, as at .15.

The, j main frame consists of a U-shaped 7 frame which I have designated l0,"uprights 11 extending therefroinand an upper frame 12 supported'at the top of theuprights. The sill is attached to the binder frameby'mea'ns;

of extensions'l'3 attached thereto, which e'xtensions are'adjustably connected to exten- After the bindingoperatioln of the binder, takes place in a well known manner, the bun-v dlesare delivered by the discharge arm 20 from the binder to the shock former. The receiving portion of the latter comprises two valleys, the Valley 21 being adjacent the dis ohargeflfrom the binder and the valley 22'be-:

ing farthest therefrom. These valleys 21 and 22 are arranged lengthwise with the line of Referrmg'to the drawing whereInI have travel of the machine and are separatedaby the nearest or left hand valley 21. a When the apron 23 is in lowered position, it serves as a support-for the bundles and receives them and delivers them to the right hand or farthest valley 22L, The apron may be constructed of metal, wood or anysuitable material.

. Each valley is provided with apacker. I

have designatedthese packers as24 and25, respectively.v Thesepackers 24, 25, located respectively inthe valleys 21, 22, are of such shape and size that they will substantially equal in area the cross section of the valley, 1

with suflicient clearance, however',-to prevent clogging which might be causedby the edge of a packer beingrtoo close to the valley wall.

The packer 24: is mountedon a fsup'port 26 which is in turn carried by two chains 27, 28

extending, respectively, along the inside and outside of thevalley E21 and at thefioor level thereof, the upper reach of each chain being low thereof,

The shaft 31 is provided at its inner end with a he vel pinion 32 whi ch meshes with a bevel gear 33. 1

Similarly the packer 25 is mounted on a support '34; which is carried by chains similar in construction to the chain 2?, which chains are supported at the front end through the sprockets 35 by the shaft 36. The shaft gears 32 and 3;? are in mesh with the hevel gear'33 on opposite sides any ro ary movementof the .gear 33, wilii cause rotation of the gears and 3"? in opposite directions. it will thns be seen that the packers will be moved in opposite directions by a rotation of on the saine shaft witn the gear" 33 and ted by a seglnental gear 89.n1ounted to re- 41' oft'he partitionbetween the valleys. A rack 42 is in operative engr ment; with the segmental 'gear 39 and has a geared bar 43w; its opposite end. "This geared bar has an There is sufficient space between the frame 4a and the bar 43, to permit the relati-vejpassage of the gear 45 which ,is mounted on the shaft 46 the latter of which s mounted ad- ;acent the side of the mainframe and extends in .a fore and aft direction and while rotat r-abl yljournaledr maintains its axis in a fixed position relative to the frnain frame.

The sprocket 458 is driven from the power chain 50of the binder in a manner to be described. I f 1 i Connected to one end of the rack is a flexible cord member 51 which passes over the pulley 52 and the pulley 52" and is connected to the apron 23 as at 53L "The connection of L2 is at such a place that when the rack when Fig. 'lfthe apron 23 will he in iowered position to direct the bundles to the outside .or

Thetwo inner walls 61 of these cham- "bers are pivoted together. at "heir upper ed 'es, the lower edges beingseparated to cause 'thebundles e'fjthetwo chambers to lean toward each other in order tribe in this position when deposited jupon' "the ground each row of bundles thus forniingia support for I The walls 60, 61ers supported by means of hangers 02,63 which are respective iy suspended frond shafts ht, 65 supported from the framemembers 12. The hanger 63 performs the functioniof a lever since between the supported and supporting ends thereof, s a shaft to which is attached a pitinan .66 which at its forward end is connect- .ed to a crank 67 of the crank shaft 68. S11 the crankshaft 68 1s keycd'a' sprocket wheel 69 which is connected by a chainZ O to another sprocket wheel T l whichis l.:ved on the shaft 72. A r-tone end of the shaft 72 is a bevel pinion 73 which meshes with a bevel pinion 74L mounted to rotate with thesnaftf'fi.

f t the lower end of the shart to is a bevelpinion 76 which is slidably keyed thereon. "Wl-Ien in the lowered position, the pinion/I6 V a bevel pinion 7? which run centinueusly.

A sprocket 78 is fiX-edto the p nion 77. A sprocl ret chain LTQengag-esthe sprocket T8 and also thesprocket 8O arranged to rotate with the sprocket 81which latter operated .by the drive chain 50 of the binder. The

sprocket 48 is integral with the sprocket 78, and is continuously driven thereby.

In positiontoengage the chain 79 is large segmental sprocket 82 having teeth onfhalf of its circumference. H On the side of the are mental gear-fie secured track composed of the outsideinernber83 and" the side member 84. A lever85ifulcr1irned at 86 carries the roller 87411; itsou'ter endnndat its inner end,1sa jaw which engages a collar 88, which is integral with the'pinion '16.

In position, to act upon thetecth of the segmental ratchet 89 is a sprocket 90 having a single pawl tooth 91 in position to engage one tooth of the ratchet during each revolution. The sprocket 90 is inposition-tocontinuously engage the chain 92 which runs on'the sprockets 93 and 9 1, the latter being mounted'upon the shaft 95 upon which is also mounted the discharge arm 20 of the binder. The gear ratio between the sprocket 94sand the sprocket 90 is 1 to 1 so that a revolution of the discharge arm causes one revolutionof the sprocket 90.

and a consequent advance in rotation of the segmental sprocketSQ'equal to the angle occupied by one tooth of the ratchet 89. The angular movement of the segmental sprocket 82 caused bythe angular travel, which results from eight, revolutions of "thesprocket 90, is equal to the angle of the outert rack Each time the sprocket 9 1 with the dis charge arm 20 makes eight revolutions, the

roller 87 is'raieed by the inner track 8 which, through the lever 85, causes the gear 76 to mesh withthe'gear T'T-which causes the shaft to be turned.- This'causes movement to be transmitted through thepinions 7 1, 73, shaft 72, sprocket 71, chain 70, sprocket 69, crank shaft 68, crank 67, pitman 66 to the lever-hanger 6 3. 'As the hanger 63 is pushed rearwardly, the inner walls 60,61 of the shock receptacle are moved to the rearand upward. At the same time, they are collapsed together, the outer walls move to'the rearward and the floor members are released, all in a manner to be described.

By the time the shock receptacle empties-its shock, the segmental sprocket 82- will have rotated to a point where it has no further teeth to engage the chain 7 9. At this point,

the roller 87' engages the outer track and the roller end of the lever is lowered to raise the pinion 76 out of engagement with the gear 77. This permits the whole t"9.111 of gearing which raised the members 60, 61'to be free.

The weight of the members 60, 61 causes them" 79 with the simultaneous placing of the gear, '76 in mesh with the gear 7 7 for another shock discharging operation. 7 Y I ,7

In order to have a means for setting the sprocket 941 to any part1cular position relative to the shaft 95, to facilitate the proper setting of the parts as atthe beginningof a ,days work, I provide a spring operated clutch member 96 which iske-yed to the shaft 95. The sprocket 9 1 is freely-mounted on the shaft and, when in engagement with -the clutch men'lber 96, ,will revolve therewith.

.The sprocket 94 and'the clutch member 96 have cooperating teeth which, while they hold together under normal operation, will slip in case any of the driven gearing becomes stopped" from abnormal causes. In such a case,.there is no breakage, the teeth permitting the sprockett'o stop while the shaft 95:

with the clutch member 96 would continue to revolve. I

Parallel to the shaft 72 is a shaft 100 sup ported fromthe frame members 12. At each end of'this shaft 100 is a'bevel gear 101 which coacts with bevel gears lt on the shafts 103. one end of the shaft 100is also a sprocket 10% which is driven from the chain 105 and the sprocket 106 which latter rotates withthe shaft72.

115 are provided to hold the walls109 outwardly. On each of the cranks 10'? is provided a wheel 116 against which the wall'109 rests. It is to-be noted that the walls 109 of the shock forming receptacle are separate 12mm m er walls 117" of the respective valleys 21 a d 22;

When the shaft 72 revolves, as already de- I scribed, motion is transmitted through the sprocket 106,'cliain 105, sprocket 10 1, shaft 100,- gears 101, pinions 102, shafts 103, cranks 10'? to the connecting rods 108 which inove'the walls 109 rearwardly during the dumping operation. After the completion of the dumping operation, the inner walls 60, 61 move forwardly, as already described and the outer walls 109 also move foriv'ardly to their respective initial positions.

fit the outer ends of each shaft 6e,- '65,is a. crank to which respective cranks are pivotally attached rods 121 which extend to hell crank levers, upon one end of each of which is a notch 121 in engagementwith the arms 122 which extend from the pivoted receptacle floors 123'. It WllltllllS be seen that assoon as the cranks 120 are moved out of alignment with, the rods 121, the downward pre of the shock-uponflm floors 123 will cause the floor members 123 to fall and dump the bundles thereon. Suitable spring men hers 123 are preferably provided of sufficient as av center.

strength to lift the floor members 123 when the shock receptacle is empty but ineffective to support the bundles after the disengagement of the notch121 with the end of the arm 122, caused by the "turning of the cranks 120, as already described.

As previously described, the operation of the crank 67 on the hangers 63, causes the innor walls 60, 61 of the shock former to move to the rear. lVhen this takes place, the two walls, which are hinged together at. their upper edges, collapse against each other.

In order to bring about this result, I provide a series of pairs of links 130 pivoted together at their inner ends and having their outer ends pivoted to the walls and 61. These inner ends are connected by a longtudinally extending control bar 131.- This bar 131 is connected at its middle by a bar 132 which latter is connected at its upper end by a lever 33. The-lever 133 is pivoted at 134 to a block supported in a cut away portion of the innerwalls 60, 61. The upper end of the lever 133 is connected to a link 135 which extendsrearwardly and connects to the frame at 136.

lVhen the inner walls 60, 61 move rearwardly, the fulcrum of the lever, 133 moves rearwardly, turning the lower end thereof, relative to the walls 60, 61, about the pivot 13a This causes the link 132 to be lifted, bending the toggles formed of the links 130 and permitting the walls 60, 61 to collapse. As the walls 60, 61 swing to the rear, theparts return to the former position causing thewalls to be again spread apart.

The bundles, when delivered from the binder, are in a horizontal position. I have provided means for straighteningthe bundles so that when they are in the valleys, they may be in an upright position to be packed and delivered to the ground in a standing position. The numeral 136Pdesignates the supporting levers which are secured to the inner walls 60 and 61 of the shock forming receptacle. The lower end of these levers 136 are bent and have attached thereto arms 13'? which are in position to support the upper ends of the bundles when being delivered.

Theconnectionsbetween the levers 136 and the respective arms 137 are rule joints permitting movement in arearward direction to permit a bundle topass when forced by the packers 2a and 25.. The springs 136, however, normally tend to hold the arms 137 in positions perpendicular to the line of travel and in substantially horizontal planes.

As the packers return to forward positions,

the arms 136 also return to their normal positions. The levers 136 are adjustably supported so that they may be swung and raised or lowered to place the parts in proper ad- 7 justment.

As already described, the discharge arm 20 of the binder 1s operated whenever a bundle is ready to be operated. V The control for the operation of this arm is a part of the hind- 1ng mechanlsm and wlll' not be here described as also hereinbelore stated, the gear 77 is driven continuously as is also the sprocket at its lower end to an inverted U-shaped shifting device 138. This shitting device straddles a. sleeve 139 which is mounted on,

the shaft 16 and carries the sprocket l? on its outer surface. Thesleeve 139 is provided at its ends with collars 140 andlll, the latter having a sliding "connection with a the sprocketd'? on theshattetl. The sprocket 47 has a plate which is provided with holes cooperating with the teats 142. The slope of the sides of the tea-ts is such that'they will not clutch with their openings unless posi ively held in cooperation. I The rod 137 has a flange the shifting device 138 when the rod is forced downwardly, the portion of the rod within the shifting device 138 beingotherwise tree to move vertically.

The chain 49 is provided with two lugs 145 which are oppositely spaced thereon and in position to engage the lug 1&601? the shifting device 138, to raise the latterfroin its lower position.

The number of links of the chain 49 bears the same ratio to the number-oi teeth of the sprocket 4:7 as the number of teeth in the rack 43 bears to the number of teeth in the gear 15. p

When a bundle is ready to be discharged to the shocker, the discharge arm 20 operates which causes therod 137 to be placed under compression. The flange ll-l engages the shifting device 138, the cam 138 of which causes the shifting of the sleeve 139 and the engagementof the teats 14-2 with the corresponding openings ofthe sprocket A7. As the sleeve 139 is keyed to the shaft d6,the motion of the sprocket 17 is transmitted to the shaft 46 therethrough; As the shaft 46 turns, the

gear 45 is turned, the rack 41-3 is moved and the packers alternate,'one moving forwardly, the other rearwardly. This operation has already been described.

Asthe shaft 95 continuesto rotate, to complete its cycle, the shifting device 138 does not necessarily disconnect. This is due to the fact that the rod 137-is free to'move upwardly as already described. When, however, a lug 144 which engages the collar 140, the shape of the teatscauses them to be disengaged. from their openingsand thus. stopping the operation of vthe sprocket 47. The parts are now ready for another operation wherein the packer of one side will move to the vforward position and the other will move to the rearward position.

Having described the details of construction and operation of theseseveral detailed parts, I will now describe the operation of the device as a whole The grain is bundled by the binder in the usual way and the bundles are delivered to the shock forming machine by the arm 20.

As already described the alternate bundles will be delivered to the respective valleys'21, 22 depending upon whether the apron 23 is in upper or lowered position. WVhile one of the valleys is receiving a bundle, the packer 24 or 25 is packing the previously received bundles towardthe rear and into the shock receiving receptacle. The operation of the apron 23 and of the packers 24, 25 is as already described, coordinated with the action of the bundle delivering arm 20. When the required number of bundles are in the receptacle, the gear 82 causes the connection of the gear 76 with the gear 77. This causes the whole dumping mechanism to be placed in action, the inner Walls 60, 61 to move rearwardly and collapse, the outer walls 109, are moved rearwardly and the bottoms 123 are caused to be dumped. Due to gravity and springs, as already described, the parts re- 7 turn to their normal position and the shock receptacle is again ready to receive bundles.

While I have shown and described one embodiment of my invention, I desire'to have it understood that I do not limit myself to the exact showing and that modifications and changes may be madewithout departing from the spirit of my invention and within the scope of the appended claims.
